Curious of penis enlargement from a 3 inch perspective

Hi. My penis is around 3 inches erect and I was worried that I would not be able to satisfy any future partner of mine and I stumbled on this community. I just have a few questions:

What enlargement tool and method did you use? How much larger from a 3inch did you go and how much time did it take? How did you feel after the enlargement? Were there any negative side effects both physical and mental? What changes, if any did you see in your sex life, especially with a partner that experienced your changes?
